a year has 52 weeks , meaning 52 gaming evenings ( a sunday )
a sunday consists of 24 hours , however thats undoable for some (heh)
lets state thats effective 3 hours of gameplay
depending on the map but for the example i pick beach which i think is 10 mins @ stopwatch ( lets keep the math simple for now )
u can play 1 round in 10 mins , so 2 rounds is 20 mins , is effective 3 times the map in 1 hour , so in 3 hours u have played the map 9 times both ways.. eg 18 rounds in 3 hours ( 6 x 3 is 18 .. dont loose me now just yet)

so lets the basic value at 52 as 100% ( as days )
to get in detail thats in hours times 3 ( 156 hours a year = 100% )
the effective rounds on beach a year= is 2808 ( as 100% )
so this might be a rewarding system for just beeing there ..
( nothing fancy yet .. u can make it as fancy as u will ) but i think we might need to keep it simple.. (ahem) .. but we need a start value for something to compete against .. this is needed to get your frags a match
and statistics on who is the best player , engineer , whatever

example every player has 2808 points ( 1 point a round based on beach)
so lets say he/she shoots 1 player a round this would resolve in
2808 points a year + 2808 kills = 5616 points a year
is 108 points a week is 36 points an hour ( 1 point for beeing there 1 point a frag ) .. this is based on Deathmatch, so to make some honest statistics im open for ideas , eg healing a player , supplying ammo to a player , planting dynomite etc .. using the above example i hope someone has a bright idea
